Specification of Letters Patent.

Patented Sept.. 6. 119ML Application filed ebrnary 18, 1909. Serial No. 478,686.

To all ywhom "il may concern:

lie ity known that l, Jonx C. Baluma, a Citizen of the United States, residing atI Chit-ago. in the eounty of Cool: and State of lllinois. have invented eertain new and useful Improvements in VCenterJBearings for Cars; and l (lo herebv declare the following,` tobe a full. clear. and exact description of the invention. such as will enable others skilled in the art to which it. appertains to make and use the same.

.\l v invention has 't'or its ohjeet. to provide au improved renter heal-i119r tor ears, and to this end. it. eonsists ot` the novel devices and eomliinations ot' deviees hereinafter de.- serioed and delined in the claims.

ln the accompanying drawings' which illustrate this invention, like characters indicate like parte throughout the several 'views.

llet'erringcil to the drawings: Figure l is a bottom plan view with parte hrolnin'aimy showing the improved renter hearing; and Fig. 2 is a vertical section taken on the line afl .r2 ot Fig'. l.

[is the salient teature ot the present invention. the renter hearing' is made up ot' upper and lower roller bearing, plates, interposed rollers', and a .so-called anchoring plate Conner-ted to one of the roller bearingpla-tos h v teleseoping huh portions'.l This permits the roller hearingsproper, to-wit, the upper and lower l `ariugl plates and the interposed rollers. to he. ot' standard construction, requiring only the s'o-e: lletl anehoring plate to lie made in vanvingl forms to suit arsof ditlereut tlesib. lsuch as' employed on tlitl'erent roatls,*or l'eetpiently-` hy the vsame roads.

'l`he invention as pret'erahly constructed, and illustrated in the drawings, is as tol lows: rl`he uumerals'l and 2 indieate resi e .ti\:el v,tln\. lower and upper roller l'iear- .in eA plates. and the numeral Il indieates the so-ealletl anehoring` plate. "lhe roller hearing platea l and 'i Iire tol'med with out,- wardlj.' diveng'iirg` annular roller hearingl .sui-laresl lietweeu whirh. eouieal hearing rollers l are interposed in radial arrange meut and iu eiose rontaet. l`lie lower roller hearing" plate l termed with a largeaxial passage and with an upwardlyv extended hul) [lange .3 .surrouinling .said passage; and is also l'ormed with a hase [lange t3 adapting it; to he bolted to a trut-.ltr holster, not shown. rthe upper roller hearingplate 2 is Vformed with a de )endine' annular` thrust tlanee 7 With 'whieh the rounded outer ends of the hearlne` rollers l engage, and is also formed with a central approximately cylindrical, butt.;

preferably slightly tapered, hub flange 8, that telescopes through and worlfzs pivotally within the axial passage of the lowerfroller hearing` plate l. An annular retaining rn t) shown as' riveted to an inwardly extentie annular portion ol the huh flange 8 projects under the hul) flange ol? the lower roll-ei: hearing' plate l. and locks the two roller hearingplates together, while permitting the pivotal movements thereo-l in respect to eaeh other. The roller bearing` pro `er is thus eonneeted in au assembled eonitien, and the rollers will he held in place even when the said eenter bearing proper is re! moved trom workingA position. The lower iii-turned portion of the huh tlange 8, and the retaining rioreT tl are toi-ined with a central passage lt), through whieh a king bolt. or center pin, not` shown, may be passed. rlhe anehoring plate El rests loosely upon the upper portion ot' the upper roller nearing plate L. and is provided with a sleeve like huh ll that depends therefrom and loosely telescopes into the hul) tlange 8 'of said upper roller hearing plate. with its axial passage alined with the said .passage l0. Also, this anchoringplate 3 is provi ed with extended flanges 1Q that are adapted to be holted to the ear holster, not. shown. Cle- .\.iretl. ol: course. this anehoringg,` plate 3 may he positivenr seein-ed by bolts, rivets or oth.i erwise. to the upper roller hearing l-te 2, hut in praetiee this is not neeessary, eca'nse the trietional engagement between thetwo plate` 2 autl 3, being much greater tlian'the t'rietion lletween thel rollers and the upper hearingh plate 2, will cause the two said plates 2 and .53 to rotate together in service.

ln prat-tire. the roller bearing plates-l and whirh as aliove stated. are malle in .standard siizes. are trop torfgjinlf: preferably oll ysteel. and these atl'ortl very hard hearing surlaees l'or the rollers; and the ant-lening plate il is usually made ot tashatecl and is the ont)Y part ot' the hearing that requires special designing to adapt. the hearing; to the ram otl tlitlerent roadsl or tlitterent de- 'l`his does away with a very large expense whieh would ,otherwise he ine-ident to adapting` the entire hearing to different ear-eonetrnrtioin Sliflih'.

t will, of course, be understood, that the center bearing described, might be turned upside down, with a so-oalled anchoring plate at the bottom of the bearing, but by far the best results are obtained by placing this anchoring plate on top of the upper center bearing as illustrated in Fig. :2 of the drawing. It will therefore, he understood, that the center bearing is Capable of various other modifications Within the sii-ope of this invention.

liv/hat I claim is: i

'1. A center bearing comprising upper and lower roller beerin plates and interposed rollers, one of said earing plateshaving a sleevelik hub telescopedthrough the other bearing plate and provided with a projectin retaininn ring or flange holding the said plates interlocked but free for rotation, and an anchoring plate having a sleevelike hub telesco ed into the sleevelike hubef the engaged nearing plate, and the sleevelike hub of the said anchoring plate affordingv an extended bearing for a king bolt or center pin, substantially as described.

v2. Av 'center bearing comprising upper and lower renter bearing plates and interposed radially disposed rollers, one of said bear-` ing plates having a sleerelike hub telescoped through the other bearing plate and having, also, an outer thrust flange for engagement of the ends of the rollers, the said sleevelike hub having an inwardly extended flange and a. retaining ring riveted thereto and serving to hold the said bearing plates interlockwl but ilree Jor rotation, and an anchoring plato having asloerclike huh telescopcd into the slrmelike hub of said bearing plate, with the passage thereof alined with the passages through said in 'ardly extended flange and retaining ring, tho said alined passages affording an extended seat for a king bolt,` or Center pin, suhstantiallyas described.

In testin'lony whereof I ailix my signature in presence ot' two witnesses.
